Report
The team at Sub-Zero went above and beyond our expectations. Will spent the time to run through our house plan and provide recommendations on what would work best for our space and was always available to answer any questions we had. From our initial consultation through to the installation of our unit, Will communicated and worked in with some fairly tight timeframes to ensure we had the installation completed in time. If you are looking for quality work, product and people, definitely give the guys at Sub-Zero a call.

We used Sub Zero to install our split system air conditioners. Will and his team were very professional and prompt. Tony and Stewart did a very clean job at installing these systems at our place. They were also able to give us a good package deal on the brand of our choice. We highly recommended Sub Zero to anyone looking to do their next air con install.

Highly recommend William and the team. They installed our ‘My Air’ ducted air conditioning system at our residential home and the work was excellent. William’s customer service has been amazing answering any… questions we have had. Stuart also did a maintenance service on our units and he was thorough and completed the job in an efficient time. Highly recommend Sub-Zero Air Conditioning.
